TPU 3d printed texture
I was looking for the same thing and decided to make a TPU material myself. I did it using a brick texture with the row height set really high, brick width set low, and mortar thickness very low to create tightly spaced long thin vertical line and feeding that into the Normal socket. You could experiment with mixing the Brick Texture with a Noise Texture to give it some more randomness, or by feeding the brick texture into the Color socket, varying the brick colors and changing the Brick Texture Bias setting to give it more color variance between the lines.
